BL8072 2A Low Consumption Linear Regulator DESCRIPTION FEATURES      BL8072 is a series of low power consumption, low dropout voltage regulator with a typical dropout voltage of 1.0V at 2A load current. BL8072 can provide output value in the range of 1.2V~5.0V in 0.1V steps. It also can customized on command.   Other than every voltage version can be used as an adjustable voltage version, with which desired voltage can be achieved by setting the values of two external resistors of the application circuitry.  APPLICATIONS BL8072 has well load transient response and good temperature characteristic, And it uses trimming technique to guarantee output voltage accuracy within±2%.     BL8072 series is available in standard packages of SOT-223 and TO-252.
